G'day John, I just let nature take it's course. I have never caged any queens. I don't break queen cells down, however if I find queen cells on more than one frame, sometimes I'll remove a frame to add to another split to speed things up for that split. Having said that, I'm aware that the more queen cells a split has, the better the chance of that split producing a strong queen. If we allow a split/colony to have only one queen cell, chances are that that queen might be the runt of the batch.
